• assertArraysEqual(arr1, arr2): determines if two arrays are equal.
• assertEqual(val1, val2): assess whether two arrays are equal, and returns true or false.
• assertObjectsEqual(obj1, obj2: assess whether two objects are equal, and returns true or false.
• countLetters(str): returns an object with the count of letters in argument string.
• countOnly(arrSource, objToCount): determines number of times a value occurs in an array, and returns an object.
• eqObjects(obj1, obj2): returns true for 2 equal objects, and false for 2 non equal
• findKey(obj, cb): returns first key in obj which valuates true in cb
• findKeyByValue(obj, val): returns first property in obj with value(val)
• letterPositions(str):takes in a sentence, and returns an object with the indexes of every letter in the sentece.
• head(arr): returns the first element of an array.
